Application filed November 1, 1910. Serial No. 590,118.

To all whom it may concern:

Be it known. that I, ALFRED G. F. KU- nowsnr, a citizenof the UnitedStates, residing in the borough of Brooklyn, city of New York, in thecounty of Kings and State of New York, have invented certain new anduseful Improvements in Type-Writing Machines, of which the following isa specitication.

This invention relates to locking means to "retain paper guiding deviceswhere adjusted along a typewriter platen, and con stitutes animprovement upon a portion of the device disclosed in the application ofFrank A. Young, filed October 7, 1910, Serial No. 585,752. In saidapplication a pa per guide and roll are mounted on an arm hinged to aslidable mount or clip, the latter being fitted to a guide rod and theguide being pressed toward the platen by a spring.

I have provided an improved positive lock,

to hold the bracket where adjusted said lock comprisinga dog arrangedinternally of a barrel that is journaled on the rod and confined betweenarms formed on the mount, said tooth engaging a rack formed on the rod.A finger piece on the barrel turns the same to release the dog. The rodis oblong in cross section to fit guide holes in the mount, so that thelatter may not turn, while said barrel tits on the rod in a man-. her tobe capable of rotation thereon. M

Other objects and advantages will herein? after appear.

In the accompanying drawings, Figure 1 is a perspective, showing theinvention ap plied to the platen frame of an Underwood writing machine.Fig. 2 is a section through the locking barrel. Fig. 8 is a rear perspective of a paper finger, showing the guide rod and rack. Fig. 1 is across section, showing the mount locked to the guide rod. Fig. 5 showsthe mount released. Fig. 6 is a detail, showing the mount and guide rod.

Types 1 strike a platen 2 on anaxle 3 journaled in the ends 4: of aplaten frame, said ends connected by a paper shelf 5. The sheets aredrqpped between the paper shelf and platen, and are fed beneath theplaten by the usual rear and front feed rolls and 7. After leaving thefront guide roll 7, the leading edge of the sheet rises and is caught bya downwardly-extending'finger 8, which conducts the sheet up in front ofthe platen and under a feed roll 9 running on the platen, after which arearwardly-extending finger 8 directs the rising sheet backwardly overthe platen.

The paper guides and holders are preferably arranged in pairs, one foreach side edge of the sheet, the guide fingers 8; 8 and roll 9 beingpivoted on inwardly projecting pins 10 carried by arms 11 each pivotedbe: tween ears or arms 12, 12, preferably integral with a sliding clip,bracket or mount 13. A spring 1d on the mount bears against a projection11 formed on the inner end of the arm 11, to press the roll 9 normallyagainst the platen, (Fig. 1). lWhen the arm 11 is swung up out of theway, (Fig. 6) the spring engages a dwell portion 1 1 to hold the guidefingers and roll idle. The mounts 13 are each supported for adjustmentto different widths of sheets, on a guide rod 15 extending between theplaten ends, said rod passing through bearings formed in the arms 12, 12and through an aperture 19 in, a steadying arm 20. (forming part of themount) parallel with the arms 12, 12*. The aperture 17 in arm 12 andaperture 19 in the arm 20 may conform to the-contour of the rod whichmay be flattened at 16, to prevent the mount from turning thereon. Thisform may be produced by cutting away opposite sides of a cylindricalrod, so that it will be oblong in cross section, as illustrated.

The .mounts are each positively locked I where adjusted, by aninternal-dog 21 projecting from'the inner side of a collar or barrel 22journ'aled on the cylindrical sides of the rod 15, and confined betweenthe in ner arm 12 and the steadying arm 20. -Said dog 21 is held inengagement with a rack 23 on the rod, by a spring 2 1, coiled around therod within the barrel, its ends engaging the barrel and the bearing 20respectively. By pressing forwardly on a finger piece projecting fromthe barrel up through a slot 26 in the mount 13, the barrel is turned torelease the dog 21 from the rack 23 and enable the guide fingers androll to be adjusted along the rod 15. The releasing pressure on thefinger piece causes the latter to bear against one end of the slot 26and thereby rock the mount slightly forward about the rod (see Fig. 6),to lift the corners 27 of the angular apertures 17 and 19 oifthe rackteeth 23. (which are cut in one corner of the, rod 15), to avoid noisefrom the teeth in shifting themount along the ioo ' rack,
